The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Gas Gauge issues

If your gauge works, it's the sending unit (assuming you have good connections).

If it's the sending unit, it could be:
1. the resister in the unit, or
2. the float

If your gauge reads properly when you move your float up and down, as Bartamos outlined, it's your float. You may have a brass float and what happens is they develop a pin hole in them over time. Then they fill with fuel and your gauge reads "E". If this is the case, just replace your brass float ($6 at laps or online).
